初中英語語法大全：狀語從句

1狀語從句

在復(fù)合句中，修飾主句中的動(dòng)詞、形容詞或副詞等的從句叫狀語從句。狀語從句根據(jù)它表達(dá)的意思可分為時(shí)間、地點(diǎn)、原因、目的、結(jié)果、讓步、比較（或方式）和條件等類。

1.時(shí)間狀語從句

引導(dǎo)連詞有when，while，till，not…until，since，after ,before ,as soon as

The bus won’t start until everybody gets on.

公共汽車直到每人都上車為止，才開動(dòng)。

When he knocked at the door I was cooking.

當(dāng)他敲門時(shí)，我正在煮飯。

Last night before he came back home, his wife had already cooked dinner and waited for 2 hours.

昨天晚上在他回到家之前，他的妻子已經(jīng)做好晚飯足足等了他兩小時(shí)之久。

After I went to church, I went shopping.

2.地點(diǎn)狀語從句

地點(diǎn)狀語從句通常由where, wherever 引導(dǎo)。

Where there is a will, there is a way.  哪里有志向，哪里就有出路。有志者事竟成。

Where there is a life, there is a hope.   哪里有生命，哪里就有希望。 留得青山在，不怕沒柴燒。

Wherever you go, whatever you do,  I will be right here waiting for you.

不管你去哪里，不管你做什么，我都會(huì)在此守侯你。

3.原因狀語從句

引導(dǎo)連詞有because，as, since。

He didn′t see the film because he had seen it.

他沒有看那部電影，因?yàn)樗呀?jīng)看過了。

They couldn’t get on the train，for it was too crowed.

比較：because, since, as和for

1）because語勢最強(qiáng)，用來說明人所不知的原因，回答why提出的問題。當(dāng)原因是顯而易見的或已為人們所知，就用as或 since。

I didn't go, because I was afraid.

Since /As the weather is so bad, we have to delay our journey.

2）由because引導(dǎo)的從句如果放在句末，且前面有逗 號(hào)，則可以用for來代替。但如果不是說明直接原因，而是多種情況加以推斷，就只能用for。

He is absent today, because / for he is ill.

He must be ill, for he is absent today.

注意：because不能和so 連用。
